PLEASE, I agree that you are not quite there yet for juice. Your body rigth know is at its prime. Even if your test level are in the low range, you are better taking advantage of your youth. Also, test levels are not the only variable in muscle development.
FOr most, the first cycle is the best one. Also, steriod work best adults. Reason being is that the body is a state that can benefit the most of the steriod usage.
The muscle that you will pack working in your youth is the best quality muscle you can adquire. Think about it them as your base/foundation. WHY SPOIL THAT with impatience.. YOU HAVE ALL THE TIME IN THE WORLD!
Aslo, most males stop growing/developing approx 23 years old. You could limit yout growth becasue most anabolic/androgenic steriods prematuraly close the epiphysial cartailage wich lead to growth stunt and ultimately result in a decreade in predicted height... this is irreversible.
